white powder. The theoretical chemical composition is 2 r02 67.2%,Si02 32.8%, relative density 4.7, melting point 2400~2500 ℃, hardness 7.5. No waste in water and acid. Good chemical stability.
after mixing zirconium quartz and Soda Ash in a certain proportion, it is sent to a high temperature furnace for roasting at about 1100 ° C. After roasting, it is pulverized and then sent to a purification tank, and then the pH value is adjusted to acid with hydrochloric acid, additives are then added to purify titanium, iron and other impurities at 60-80 °c, rinsed with water to remove insoluble salts, and the product is obtained by filtration, drying, and jet grinding.
zirconium silicate is an excellent opacifying agent, which is widely used in the production fields of high-grade ceramic glaze, advanced refractory fiber, TV display screen and so on. It is also a special glass, porcelain with raw materials and special rubber reinforced resin filler.

use | used for ceramics, opal glaze, coating enhancers, etc. catalysts for the manufacture of alkanes and alkenes. Silicone rubber stabilizer. Manufacture of metallic zirconium and zirconia. Industrial applications: zirconium raw materials, gems, catalysts, cements, glass polishes, resistors and electrical insulators, refractory materials, glazes, which play a whitening role in ceramic glazes, and can take expensive tin dioxide, Zirconium dioxide can greatly reduce the cost on the glaze, with an average particle size of 1um-1.2um. |
